地震作用下边坡稳定性分析

Analysis on Slope Stability during Earthquake

摘要:

考虑了边坡岩土体材料的动力特性以及地震特性,利用动力有限元时程分析方法对边坡在地震荷载作用下的动力特性进行了分析,采用最小平均系数对边坡稳定性进行了评价,并与拟静力法的结果进行了对比分析。对某工程实例计算结果表明该分析方法的可行性,可为地震作用下边坡工程设计工作提供一些有益的参考。

Abstract:

Dynamic fininte element method and time history analysis are explored to analyze dynamic property of slope during seismic process considering soil dynamic property and seismic characters.The minimum mean safety factor is explored to evaluate slope stability.The result is compared with the one of the pseu-static method.The result from a typical slope in a real case indicates that the method is feasible.
